The Lowdown
G'day, it's Rusty. We've got a solid run of surf coming up at Lakey Pipe, and it's almost all on. The water's sitting at a typical 80° for this time of year, so no dramas there.
We're kicking off straight away on Wednesday the 16th of September. The afternoon sees a clean 6ft SW swell with a long 14-second period pushing in. It's a cross-off breeze, so the wave faces should be tidy enough, but the energy is pumping hard at 1543 (moderate to strong). It's not the absolute best of the run, but it gets us started.
Thursday the 17th through Saturday the 19th sees consistent, clean surf with swell sizes hovering around 4ft to 7ft from the SSW and SW. The winds stay light and cross-off, keeping things lined up. The wave energy is moderate for most of this stretch. It's all good, fun surfing.
Now, the first real standout hits on Sunday the 20th of September. The morning brings a 6ft SW groundswell with a very long 17-second period, and the energy jumps to 2118 (strong). By the afternoon, it's even better: 7ft SW at 16 seconds with 2192 energy. The wind stays light and cross-off. For an exposed reef like Lakey Pipe, that long-period SW groundswell is going to wrap in clean and powerful. It's an expert-level wave size, but the quality is going to be outstanding. This is the one to point your board at early.
Monday the 21st keeps the party going with another 7ft SW swell in the morning, dropping slightly through the day. The next real standout is a big one for later in the run. Check out Saturday the 26th of September. It looks small on the face, at 3ft to 4ft, but don't be fooled. That's a 23-second period SW groundswell for the morning, and the energy is a massive 1745 (strong), jumping to 2338 (strong) by the afternoon. That’s some very long-period energy for a modest height. It will be a long wait between sets but the waves will have ridiculous shape and push. Perfect for experienced surfers looking for clean lines over a reef.
For the final week, we get another big pulse. Sunday the 27th of September pushes 10ft from the SSW with 18 seconds – that's 6254 energy (very strong). That is absolutely maxing out the break. The finder's flagged it as too big for this spot, so only the absolute lunatics should even look at it. Monday the 28th is still giant at 8ft for experts, then it settles back into the 5ft to 7ft range through until the end of the month and into October. The Thursday the 1st of October morning session looks like another strong, clean offering.
The real winners here are Sunday the 20th for that big, clean SW groundswell, and then Saturday the 26th for the freakishly long-period glassy lines. The whole stretch is consistent, but those two dates are the standouts. Crowds are always a factor here at Lakey Pipe, so get there early.
Rusty.

Information about the Lakey Pipe Surf forecast
The above surf forecast table for Lakey Pipe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lakey Pipe can be found by selecting the local surf guide option on the grey menu. Our Lakey Pipe surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Lakey Pipe) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Lakey Pipe may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
